FeaturesBenefits
Durable CompoundA special mix of natural rubber, high strength polymers, and wear resistant materials aids cut and chip resistance on unpaved gravel roads.
Sidewall TechnologyThe staggered shoulder blocks provide biting edges for off-road traction in loose dirt surfaces. The 3-ply sidewall with large sidewall lugs offer additional sidewall strength and puncture resistance.
Winter PerformanceRated with the 3-peak mountain snowflake for winter driving conditions, the Exo Grappler’s sipes and large lateral grooves provide biting edges as well as water and snow/slush evacuation. These tread features are combined with a new durable compound that allows for traction in freezing temperatures. For additional traction, option TSMI #15 studs can be added for increased winter traction.
Variable Pitch Tread BlocksThe computer analyzed tread block arrangement reduces tire noise normally heard at highway driving speeds.
Gear Shaped Block EdgesThe gear shaped block edges reinforce center tread blocks and provide a stable contact patch. They also help reduce stone retention and stone drilling.
Stone EjectorsSpiral shaped stone ejectors serve to reduce stone retention, as well as stone drilling.
Dual Sidewall DesignsEach Grappler has two sidewall designs so you can choose how your tires look. On the Exo Grappler one side has three-dimensional butresses and the other has Y-shaped butresses. This feature was an engineering feat since even a small weight imbalance can cause unwanted vibrations. Nitto produces exceptionally uniform off-road tires even with different designs.
